Description
Technical field
The utility model relates to building engineering field, more particularly to a kind of quick chiseling pile head of armored concrete.
Background technology
Generally in pile foundation construction, chisel need to be picked in the part of pile crown top 0.8m-1m, reinforcing bar is exposed, is anchored into
In architecture basics bottom plate.Effect is bonded due to reinforcing bar and concrete, the pile crown constructed out using traditional construction method is easy
The cement mortar of the extremely difficult rejecting of pile crown concrete and rebar surface is caused to be difficult to clean off.
Utility model content
The purpose of this utility model is to provide a kind of quick chiseling pile head of armored concrete, to solve prior art construction
The technical problem that the cement mortar of the extremely difficult rejecting of pile crown concrete and rebar surface is difficult to clean off.
To achieve the above object, the utility model adopts the following technical solution.
A kind of quick chiseling pile head of armored concrete, positioned at the top of pile body, includes pile crown reinforcing bar and is cast in pile crown
Pile crown concrete outside reinforcing bar；The lower end of the pile crown reinforcing bar is embedded in pile body, and the upper end of pile crown reinforcing bar exceeds at the top of pile body,
And length of excess member is 35d；Wherein d is the diameter of pile crown reinforcing bar, and the scope of d is 20mm ~ 36mm；On the pile crown reinforcing bar
It is arranged with casing；Wherein, mouth is concordant with the top of pile body under casing, and the top of casing exceeds the top of pile crown reinforcing bar；Described sleeve pipe
Top be packed with filler, over top of the filler closure in pile crown reinforcing bar.Preferably, described sleeve pipe covers for PVC
Pipe is either PE casings or is PS casings or is PB casings.
Preferably, described sleeve pipe is that PVC casings are either PE casings or are PS casings or are PB casings.
Preferably, length of the top of described sleeve pipe beyond the top of pile crown reinforcing bar is 30mm ~ 50mm.
Preferably, the filler is that blanket is either cotton fiber or is asbestos.
Preferably, outside casing, the top of pile crown concrete exceeds the length of cannula tip for the pile crown concreting
Spend for 100mm ~ 300mm.
The utility model has the characteristics that and beneficial effect compared with prior art.
1st, the utility model is arranged casing on the outside of pile crown reinforcing bar, avoids pile crown concrete and is directly cast in pile crown steel
Effect that what the outside of muscle and pile crown reinforcing bar produced bond, the difficulty of construction during pile crown concrete chisel removal of reduction；Meanwhile in pile crown
Casing is arranged on the outside of reinforcing bar, when cutting pile crown concrete, casing plays a protective role pile crown reinforcing bar, avoids to pile crown
Reinforcing bar causes to damage.
2nd, the utility model clogs filler, when avoiding pile body casting concrete, concrete water mud stream in sleeve upper end
Enter in casing and caused by rebar surface the technical problem that is difficult to clean off of cement mortar.
3rd, the labor intensity that the utility model is simple in structure, reduces, and significantly improve and cut pile crown coagulation
The construction efficiency of soil.
Brief description of the drawings
The utility model is described in more detail below in conjunction with the accompanying drawings.
Fig. 1 is the structure diagram of the utility model.
Reference numeral：1- pile bodies, 2- pile crowns reinforcing bar, 3- pile crowns concrete, 4- casings, 5- fillers.
Embodiment
As shown in Figure 1, this quick chiseling pile head of armored concrete, positioned at the top of pile body 1, includes pile crown reinforcing bar 2
With the pile crown concrete 3 being cast in outside pile crown reinforcing bar 2；The lower end of the pile crown reinforcing bar 2 is embedded in pile body 1, pile crown reinforcing bar 2
Upper end is beyond the top of pile body 1, and length of excess member is 35d；Wherein d is the diameter of pile crown reinforcing bar 2, the scope of d for 20mm ~
36mm；Casing 4 is arranged with the pile crown reinforcing bar 2；Wherein, 4 times mouths of casing are concordant with the top of pile body 1, and the top of casing 4 exceeds
The top of pile crown reinforcing bar 2；The top of described sleeve pipe 4 is packed with filler 5, and the filler 5 is blocked at the top of pile crown reinforcing bar 2
Top.
In the present embodiment, described sleeve pipe 4 is PVC casings.
Certainly in other embodiments, described sleeve pipe 4 can also be that PE casings are either PS casings or are PB casings.
In the present embodiment, the length that the top of described sleeve pipe 4 exceeds the top of pile crown reinforcing bar 2 is 30mm ~ 50mm.
In the present embodiment, the filler 5 is blanket.
Certainly in other embodiments, the filler 5 can also be cotton fiber or be asbestos.
In the present embodiment, the pile crown concrete 3 is cast in outside casing 4, and the top of pile crown concrete 3 is pushed up beyond casing 4
The length in portion is 100mm ~ 300mm
In the present embodiment, the pile body 1 is basic stake body；It is as follows that the work progress of utility model includes step.
Step 1: the steel reinforcement cage of binding pile body 1, reserves the pile crown reinforcing bar 2 at the top of pile body 1；
Step 2: being arranged casing 4 on pile crown reinforcing bar 2, the top of casing 4 is set to exceed the top of pile crown reinforcing bar 2.
Step 3: filler 5 is clogged in 4 upper end of casing, to ensure that concrete water mud may not flow into casing 4.
Step 4: pouring for 1 concrete of pile body is then carried out,, can be straight along line of cut chiseling pile head concrete 3 after pile
Connect and separate pile crown concrete 3 and pile crown reinforcing bar 2, without the concrete that 2 surface of pile crown reinforcing bar is stayed in when picking chisel traditional construction.
Above-described embodiment is not the exhaustion of embodiment, can also there is other embodiments, and above-described embodiment purpose exists
In explanation the utility model, and unrestricted the scope of protection of the utility model, it is all by the utility model simple change and Lai
Using all falling within the scope of protection of the utility model.
